[57] ABSTRACT A device for drawing out tape material which has a hand lever actuated ratchet wheel actuating a swinging arm which in turn engages a chain for drawing the tape from a tape supply each time the arm is moved.

3 Claims, 4 Drawing Figures Pmm m mm 1 ms SHEU 1 [If 2 APPARATUS DRAWING-OUT FOR WINDING TAPE This invention relates to a novel drawing-out apparatus for winding tape and more particularly to a drawing-out apparatus for adhesive winding tape.

In drawing out tape, especially, adhesive winding tape by means of devices, the difficulties is encountered in the operation. The drawing-out with hand is also uneasy matter. Some automatic modification have been developed to improve its performance and easy handling drawing-out automatically by definite amount has not attained. However, there have not been developed any type of apparatus which permits automatic drawing by definite amount.

An object of the invention is to provide an improved apparatus for drawing-out tape especially adhesive type tape mechanically.

Endless band-shaped chain having such surface so that only tape may be tensioned between shaft smallsized pully and chain drive pully. This make it possible that tape adhering to the flat surface is stripped when only tape is drown out. Further, roller is equipped opposite to clip roller. This permits the drawing-out of tape base. Sharp angle shaft is loosely mounted Blade is nearest to exit of chain which is placed, this makes tape fed.

The nature of the invention will be more clearly apparent by reference to the following detailed description when taken in connection with the accompanying illustration in which:

FIG. 1 is a side elevational view with parts in sections showing a modified form of apparatus for the drawingout of tape material.

FIG. 2 is a sectional view with parts in sections showing a modified form of apparatus for the drawing-out of tape material.

FIG. 3 is an operational view showing the drawingout of tape material.

FIG. 4 is another operational view showing strippingoff of label.

Vertical plate 1 is provided with shaft 2. Drive pulley 5 is mounted on shaft 2. Rachet 6 is carried on a side face of drive pulley. Pawls 7 7 are mounted on swing shaft 8 so that said pawls 7 7' are engaged with rachet 6. Base hole 8 fulcrumed at shaft 4 swings between wall plate 1 and driving pulley 5. Projection 8" is mounted on said swing arm 8 and said handle be together moved as said projection 8" sliding along the groove 1.

In lowering handling 9, said pawl 7 7 moves as projection 8" slides along with the said swing shaft 8. This permits chain 10 to move and thus crip rollers 11 11' to operate. Said vertical plate 1 loosely carries blade 12. 13 is used only for label stripping through the use of stripping, which is in place of blade 12. Base hole 9' is mounted to 9". Winding tape 15 is supported by tape roller 14. In FIG. 2, 15' designates label.

What we claim is:

l. A tape dispenser comprising a supply reel adapted to contain a supply of tape to be dispensed, a rotatable drive pulley and a rotatable idler pulley, a tape feeding belt extending around said drive pulley and said idler pulley with a portion thereof extending between said supply reel and said idler pulley defining a path for feed of tape to be dispensed, said drive pulley having ratchet teeth around the periphery thereof, a drive arm pivoted coaxially with said drive pulley and having ratchet means on the end thereof engageable with said ratchet teeth for driving said drive pulley when said drive arm is rotated, a drive pin projecting from said drive arm, said dispenser having a guide slot concentric with the axis of said drive pulley in which said drive pin is engaged, and a drive lever pivoted on said dispenser and engageable with said drive pin for moving said pin along said guide slot when said lever is pivoted for rotating said drive pulley through said drive arm and said ratchet means for moving said tape feeding belt for dispensing a length of tape proportional to the length of said guide slot.

2. A tape dispenser as claimed in claim 1 further comprising a knife edge adjacent said idler pulley along the path of the tape dispensed when said tape feeding belt is moved.

3. A tape dispenser as claimed in claim 1 further comprising a stripping blade adjacent said idler pulley along the path of the tape dispensed when said tape feeding belt is moved for stripping backing from tape dispensed. 

1. A tape dispenser comprising a supply reel adapted to contain a supply of tape to be dispensed, a rotatable drive pulley and a rotatable idler pulley, a tape feeding belt extending around said drive pulley and said idler pulley with a portion thereof extending between said supply reel and said idler pulley defining a path for feed of tape to be dispensed, said drive pulley having ratchet teeth around the periphery thereof, a drive arm pivoted coaxially with said drive pulley and having ratchet means On the end thereof engageable with said ratchet teeth for driving said drive pulley when said drive arm is rotated, a drive pin projecting from said drive arm, said dispenser having a guide slot concentric with the axis of said drive pulley in which said drive pin is engaged, and a drive lever pivoted on said dispenser and engageable with said drive pin for moving said pin along said guide slot when said lever is pivoted for rotating said drive pulley through said drive arm and said ratchet means for moving said tape feeding belt for dispensing a length of tape proportional to the length of said guide slot.
 2. A tape dispenser as claimed in claim 1 further comprising a knife edge adjacent said idler pulley along the path of the tape dispensed when said tape feeding belt is moved.
 3. A tape dispenser as claimed in claim 1 further comprising a stripping blade adjacent said idler pulley along the path of the tape dispensed when said tape feeding belt is moved for stripping backing from tape dispensed.
